- Fix some event listeners
- Add getCompleted() promise that resolves when the dialog closes.
- Et2Dialog.alert() returns the promise directly, other static methods return the Et2Dialog to avoid breaking existing code
You can now wait for a dialog with:
Et2Dialog.show_prompt(null,"Name?").getComplete().then(([button_id,value]) => console.log(value));
or using async:
[button_id, value] = await Et2Dialog.show_prompt(null,"Name?").getComplete();
if(button_id === Et2Dialog.BUTTON_OK) {...}
